President-elect Donald Trump’s vowing to protect American-made cars through steep tariffs on imports. The problem is, there is no such thing as an all-American car.

Trump and his allies have repeatedly claimed that the countries which produce imported goods pay American tariffs but experts overwhelmingly reject that assertion, saying those costs are borne by U.S. companies and passed on to their customers.

Automakers and parts suppliers would struggle if President-elect Donald J. Trump followed through on his threat to impose 25 percent tariffs on imports from Canada and Mexico.

Trump's threatened tariffs will hit the bottom line of U.S. automakers importing vehicles, and experts say that cost will no doubt be passed on to customers.
